Between all of the Star Trek series' there have been a large number of story arcs and plot holes that a creative writer could have a lot of fun with.
I thought of a new Star Trek series I would call "Tapestry".
Each episode would start with some scene from any of the Star Trek shows that left something unanswered, or left out some backstory, or left with something seeming "unfinished".
Then, at the end of that introduction, the image freezes then turns into the appearance of a tapestry. The camera then focuses in on one character or item, zooming in until it focuses on a single thread -- it then goes "through" the tapestry to the backside, then, as initial credits roll, we follow that "thread" winding all through the backside of a tapestry, only to emerge back out the front, then pan out into the opening scene of the new episode that continues that "thread" of the story.
We could find out unanswered questions, such as what ever happened to that empath who joined with the massive organic sentient "spaceship" creature.
We could find out what Wesley and "The Traveler" were up to.
We could find out what the Gorn told his crew after getting his ass kicked by Kirk.
We could find out how Guinan and Picard first met.
For a series finale, we could end up seeing Q weaving that same Tapestry.
